The Upper Hanover Zoning Ordinance of 1987, and as subsequently amended, is hereby repealed in total; provided, however, that this repeal shall in no manner be construed as a waiver, release or relinquishment of the right to initiate, pursue or prosecute, as the case may be, any proceeding at law or in equity pertaining to any act done which would have constituted a violation of the Upper Hanover Township Zoning Ordinance of 1987, as amended.
